대기공해가 잠아의 실용형질에 미치는 영향을 알고자 일본종계통 2품종과 중국종계통 2품종을 오염상 비오염상세, 척상별로 사육하고, 또 상엽 및 잠체중의 S, Cd함량을 분석한 결과는 다음과 같다. 1. 잠아경과일수는 일본종계통은 비오염구에 비해 오염구가 2.5일 정도 중국종계통은 4일정도 지연 및 불재일하였고 세척구는 중간 정도였다. 2. 잠아 5령극대체중, 견층중, 전견중 등은 비오염구, 세척구, 오염구 순으로 성적이 떨어졌다. 3. 화용비율은 상엽처리별로 볼 때 일본종은 유의성이 없었으나 중국종은 고도의 유의성을 나타냈다. 4. 오염상엽에 대한 저항성은 일본종계통에 비하여 중국종계통이 현저하게 약하며 동일계통에서도 종간에 차가 있다. 5. 오염지역의 상엽은 비오염지역의 상엽보다 S 및 Cd의 함량이 각각 약 30%, 300%증가하였다. 6. 잠체내에서도 비오염상 급여구는 S가 0.41%, Cd 0.013ppm이고 세척상 급여구는 S가 0.52%, Cd가 0.042ppm순으로 높았다. 7. S 및 Cd의 함량이 상엽에 가시적인 피해는 나타내지 않았으나 잠아에는 피해가 심했다. 8. 잠아의 실용형질은 공해로 인한 상엽질의 악화에서 입는 피해보다 상엽에 부착된 분전의 해가 더 컸다. 9. 이상을 종합해 보면 분장지대 선정에 있어서 중국종계통은 공해지역을 피할 것이며 부득이한 경우는 상엽을 세척급여하면 현저한 효과를 거둘 수 있을 것이다. Those studies were examined rearing two varieties on Japanese descent and two varieties of Chinese descent by feeding polluted mulberry leaves, non-polluted ones and water-cleaned ones respectively to find effects of air-pollution on the economic characters of silkworms and analysis of contents of Sulphur and Cadmium in the mulberry leaves and silkworms as followings; 1) Japanese descent of polluted part was delayed about 2.5 days than non-polluted part, Chinese descent was delayed about 4 days or inequal and water-cleaned part was medium in the silkworm larval duration. 2) Results of maximum weight of 5th instar, cocoon layer weight and cocoon weight were decreased in due order non-polluted, water-cleaned and polluted in the factors of mulberry. 3) Pupal ratio of Japanese descent was not shown statistical significance, but Chinese descent was revealed it obviously in the factors of mulberry leaves. 4) In the resistance of polluted mulberry leaves, Chinese descent was feeble obviously than Japanese and there were some difference even through among the same varieties. 5) The content of S and Cd of polluted area mulberry leaves was increased about 30% respectively than non-polluted area. 6) The fed part of non-polluted mulberry leaves was S 0.41% and Cd 0.013 ppm water-cleaned part was S 0.47% and Cd 0.024 ppm and polluted part was S 0.52% and Cd 0.042 ppm in the contents of S and Cd of silkworm larvae. 7) The contents of S and Cd didn`t make visible injury in mulberry leaves but made it seriously in silkworm larvae. 8) The injury of dust on mulberry leaves was more serious than that of quality of mulberry leaves by air-pollution in the economic characters of silkworm. 9) As above results, Chinese descent should avoid contaminated area and it rearing by water-cleaned mulberry leaves can get noticable results in inevitable case on selection of parents silkworm rearingzone.

李鍾哲,崔震浹,裵啓宣,孫興大,鄭元福 東亞大學校 大學院 1980 大學院論文集 Vol.4 No.2

Performed to study on effect of economic characters and quantity of Cd in silkworm body by feeding artificial diet which aded Cd per density to all age silkworms. The results were as follows: 1. Each treated parts was a little longer than control on silkworm larval duration. 2. Growing condition of 40 ppm on the 7th day after commencement incubation was uneven and found out around 80% of 1st instar-silkworm larvae which almost didn't grow at ones of 80 ppm. 3. Maximum weight of the 5th instar, pupation ratio, weight of cocoon, weight of cocoon layer and cocoon layer ratio of parts of 1,10, and 20 ppm was a lettle higher than control, but only ones of 40 ppm was lower than those. And found out it ws chronic toxicity. 4. Each treated parts on eclosion period was longer than control. Expecially non-eclosion ratio of 40 ppm was 30%. 5. The safe level density of Cd in diet was 20 ppm. 6. Toxicity will be occurred when Cd contents in is more than 5 PPM in silkworm body.

Those studies were examined rearing two varieties on Japanese descent and two varieties of Chinese descent by feeding polluted mulberry leaves, non-polluted ones and water-cleaned ones respectively to find effects air-pollution on the economic characters of silkworms and analysis of contents of Sulphur and Cadmium in the mulberry leaves and silkworms as followings; 1) Japanese descent of polluted part was delayed about 2.5 days than non-polluted part, Chinese descent was delayed about days or inequal and water-cleaned part was medium in the silkworm larval duration. 2) Results of maximum weight of 5th instar, cocoon later weight and cocoon weight were decreased in due order non-polluted, water-cleaned and polluted in the factors of mulberry. 3) Pupal ratio of Japanese descent was not shown statistical significance, but Chinese descent was revealed it obviously in the factors of mulberry leaves. 4) In the resistance of polluted mulberry leaves, Chinese descent was feeble obviously than Japanese and there were some difference even through among the same varieties. 5) The contents of S and Cd of polluted area mulberry leaves was increased about 30% and 300% respectively than non-polluted area. 6) The fed part of non-polluted mulberry leaves was S 0.41% and Cd 0.013 ppm water-cleaned part was S 0.47% and Cd 0.024 ppm and polluted part was S 0.52% and Cd 0.042 ppm in the contents of S and Cd of silkworm larvae. 7) The contents of S and Cd didn't make visible injury in mulberry leaves but made it seriously in silkworm larvae. 8) The injury of dust on mulberry leaves was more serious than that of quality of mulberry leaves by air-pollution in the economic characters of silkworm. 9) As above results, Chinese descent should avoid contaminated area and it rearing by water-cleaned mulberry leaves can get noticable reults in inevitable case on selection of parents silkworm rearing-zone.

家蠶을 5齡起蠶과 熟蠶때에 腹部 第 2,4,6 神經球를 摘出하여 絹絲線發育, 吐絲量, Fibroin 含量比, 營繭形態 및 ??體色의 變化에 대해 試驗하였던 바 그 結果는 다음과 같다. 1. 絹絲線의 發育은 腹部 第 4,6 神經球 摘出보다 腹部 第 2 神經球 摘出이 더 크다. 2. 各 神經球 摘出은 絹絲線의 屈曲現像을 보였다. 3. 吐絲量은 腹部 第 4,6 神經球 摘出보다 腹部 第 2 神經球 摘出이 적었다. 4. 絹絲線의 發育정도와 吐絲量은 같은 傾向을 보였다. 5. 繭絲의 Fibroin 含量比는 腹部 第 6 神經球 影響이 腹部 第 2,4 神經球보다 큰 것 같다. 6. 神經球 摘出의 경우 表面의 營繭形態는 薄皮營繭이었고 腹部 第 4 神經球 摘出의 裏面의 營繭形態는 대부분 ??體半露出繭을 나타내었다. 7. 腹部 第 2,4,6 神經球는 化?? 및 ??體色의 變化에 關與할 可能性이 예상되며 앞으로 硏究할 必要가 있다고 본다. 8. 腹部 第 6 神經球는 排糞機能에 影響을 미친다. This experiment was conducted to investigate the effects of Silkgland growth, Spinning quantity, Fibroin Component ratio, Cocooning shape and changing the pupa coloration by resecting abdominal 2nd, 4th and 6th ganglia at both the time of 5 instar awakened larva and matured larva in silkworm. The results were summarized as follows: 1. Silkland growth was showed that resecting abdominal 2nd ganglion was more effective than those of abdominal 4th and 6th ganglia. 2. The shape of silkland was appeared as serpentining by resecting ganglia. 3. Spinning quantity was revealed that resecting abdominal 2nd ganglion was less than those of abdominal 4th and 6th ganglia. 4. Silkland growth and spinning quantity were revealed the same tendency in degree of increase. 5. Fibroin Component ratio of brave was seemed that abdominal 6th ganglion was moe effective than abdominal 2nd and 4th ganglia. 6. In the case of resecting ganglia, flimsy cocoon was formed at upper parts of cocoon and half of pupa body was mostly observed staying outside of cocoon in the cocoon shape at lower part of abdominal 4th ganglia. 7. Abdominal 2nd, 4th and 6th ganglia were expected to have a close connection with pupation and changing the pupa coloration. 8. Furction of evacuation was seemed to be controlled by abdominal 6th ganglia.
